I vote for Giggerata.
I never thought she added anything, and was happy to see 'er go in S1E2
(!) (one of the two bright spots in that whole feature-length epi, the
other being the shower scene), although I admit that she made a pretty
good Pope in S4.
I think the robot-head comes in second, although if you cut out his
meanderings about the love of his life (whoever that was at the time) and
Zev's/Xev's droopings over Kai, you'd cut the series length by a quarter.

I'm OK.
